stains

Stains are unwanted marks or discolorations on surfaces caused by liquids, dyes, or substances that penetrate and adhere to materials like fabric, wood, or carpet. They result from chemical reactions or physical absorption, making them difficult to remove. Common stains include coffee, wine, and grease. Effectively removing a stain usually involves identifying its source and choosing the appropriate cleaning method to break down or lift the substance without damaging the material. Understanding the nature of the stain helps in selecting the right cleaning approach for best results.
